GMC Terrain: Engine Overheating - Vehicle Checks - Vehicle Care - GMC Terrain Owner's ManualGMC Terrain: Engine Overheating

The vehicle has an indicator to warn of engine overheating. There is an engine coolant temperature warning light on the vehicle's instrument panel. See Engine Coolant Temperature Gauge on page 5‑10.

The decision may be made not to lift the hood when this warning appears, but instead get service help right away. See Roadside Assistance Program (U.S. and Canada) on page 13‑7 or Roadside Assistance Program (Mexico) on page 13‑9.

If the decision to lift the hood is made, make sure the vehicle is parked on a level surface.

Then check to see if the engine cooling fan(s) are running. If the engine is overheating, the fan(s) should be running. If they are not, do not continue to run the engine and have the vehicle serviced.

Notice: Engine damage from running the engine without coolant is not covered by the warranty.
